Calculating Nt1 in Bass  Calculating m, p and q in the Bass Model
Tatiana
How do you calculate Nt1 in the Bass formula?




Nt1Voytech Nt1 cannot be calculated.
Usually it is given, since it represents the cumulative number of adopters so far (incl. period n1).
It is the base for your estimations of p,q and m.
Once you have those p,q,m values, you can calculate Nt, Nt+1 and so on that will converge to m. 



Calculating Nt1Ram Hi, Nt1 stands for the total number or the cumulative number of consumers who have already adopted the product. For example, you might have data for weeks 110 of the product launch. Then the total number of consumers who have purchased the product till week 10 = Nt1. Hope this helps. 



Calculating other factorsNick Hi! How can you calculate the other factors, I mean m, p and q  can I use regression analyse in SPSS software? 



MarketingSiy Hey, I also want to know how to calculate the p and q number. Or are there any factors will affect p and/or q, which should be included in the marketing decision making process, i.e. advertising budget? Thanks 



Bass Curve ExampleRichard Who can give a full example of the Bass Diffusion Model with some assumptions as it appears to be a great model? 



Calculating Nt in The Bass ModelAditi Sharma, Member I have all the other values except Nt.
If I have to calculate what will be the sales in the 4 ^{th} year, how will I find it without having the value of Nt first?
